Abstract

In mobile adhoc networks, node or link failures arecommon due to frequent network partition and that problem is solved by using replication technique. In this technique, the data items are replicating on mobile hosts. Some schemes are exists to balance the trade-offs between data availability and query latency under different system settings and requirements.The problem here is this technique is not considering the relationship between the data items. Here we solve this problem by mining system and it does association rule mining using apriori algorithm to find the frequent item (FI) sets. Nodes store this FI items information in a FI table. When a particular data item is queried and if it found in the FI table, the related item is also queries and cached in the node. Extensive simulation results show that the Apriori based replication can achieve a balance between these two metrics (data availability and query latency) and provide satisfying system performance.
